Application of dynamic modelling and model‐based predictive control to enhance a cooling tower
The Canadian Journal of Chemical Engineering, EarlyView.Model predictive control (MPC) applied to improve the operation of cooling towers. Abstract Model predictive control (MPC) differs from traditional feedback control by making predictions within a time horizon, providing better control actions for the process.

Do CSR Efforts Reduce Environmental Decoupling: Evidence From S&P 500 Firms
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study investigates the impact of Corporate Social Responsibility (CSR) committees and CSR‐focused employee training on environmental decoupling. Using panel data of 2489 firm‐year observations from S&P 500 firms between 2009 and 2022, we employ fixed‐effects models to examine how CSR governance mechanisms influence the alignment between ...

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system
Deep Underground Science and Engineering, EarlyView.The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

On the limiting Pitman efficiency of some rank tests of independence
Journal of Multivariate Analysis, 1986 Kendall's tau and Spearman's rho may be expressed by the use of standard sequences with parameter \(a=1\). The paper uses the fact that the main assumption of \textit{H. S. Wieand}'s theorem [Ann. Stat. 4, 1003-1011 (1976; Zbl 0351.62033)] may be replaced by an equivalent one which is presented in section 2.

Practice adoption in MNCS: A multi‐level interactionist model of trait activation
Global Strategy Journal, EarlyView.Abstract Research Summary Sharing knowledge through organizational practices is an important source of advantage for multinational corporations (MNCs). While prior research on practice adoption by subsidiaries of MNCs has identified several individual and organizational factors, this study examines their interplay in the context of HQ‐mandated ...

On the Pitman Efficiency of One-sided Kolmogorov and Smirnov Tests for Normal Alternatives
The Annals of Mathematical Statistics, 1966 1. Summary. Lower bounds for the Pitman efficiency of the one-sided Kolmogorov test for all normal alternatives and for the Smirnov test for normal shift alternatives are obtained. In the one-sample case this does not fall below 36 per cent at the usual levels of significance and power. In the two-sample case the lower bound depends on the ratio of the

Operating in perpetual motion? Coping with the dark side of global boundary spanning
Global Strategy Journal, EarlyView.Abstract Research Summary This paper explores how individuals experience and cope with the demands of global boundary spanning in multinational enterprises (MNEs). We foreground temporary colocation as a modality through which mobile global boundary spanners repeatedly traverse multiple boundaries, triggering intense demands with adverse consequences ...

Where Projects Fail: Geospatial Evidence of Delays and Cancellations in Chinese Development Finance
Journal of International Development, EarlyView.ABSTRACT Delays and cancellations can severely undermine the effectiveness of development finance. Yet, little systematic evidence exists on where and why these disruptions occur within the rapidly expanding portfolio of Chinese‐financed development projects in Africa.

African Economic Growth Revisited
Journal of International Development, EarlyView.ABSTRACT This paper presents an updated analysis of the patterns of economic development in Africa over the last 60 years. The analysis stresses the heterogeneity of development trajectories among sub‐Saharan African (SSA) countries. We examine the joint dynamics of income and population in 35 SSA countries.

Computational StatisticsAbstract We introduce a simple and efficient sampling strategy for the Dirichlet process mixture model (DPM) and its two-parameter extension, the Poisson-Dirichlet process mixture model, also known as the Pitman-Yor process mixture model (PYM).
